New bridge design withstands typhoons, revolutionizing infrastructure in vulnerable areas.
The article discusses a cable-stayed bridge built in a typhoon-prone area, aiming to use common materials and methods for construction. The bridge, called Keelung Harbour bridge, combines features of cable-stayed and suspension bridges. It has a 1000-meter span with a 600-meter free span, providing a 4-lane motorway. The design includes concrete and steel cross sections, suspension cables, and concrete wall foundations. The ground conditions consist of gravel, sand, and solid rock. The goal was to create a new type of structure suitable for the local construction industry in a developing country.
